通常情况下,我们自定义的类如果使用equals()的话,也通常比较两个对象的“实体内容”是否相同,那么我们就需要对Object类中的 equals()进行重写; 以下手动重写equals方法: 10 class Person1{ 11 private String name; 12 private int age; 13 public String getName() { ...
当你要输出一个对象的时候。默认调取该对象的toString方法。 每个类默认继承Object对象,它里面的toString方法源码如下: public String toString() { return getClass().getName() + "@" + Integer.toHexString(hashCode()); } getClass().getName()为反射获取类名称 hashCode()为本地方法,返回对象的地址值。
